To all whom it may concern:

Be itknownlthat I, Gnonen L. Seaman, a citizen of'the United States, and a resident of the city'of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hair-Drym g Devices, of which the following is a specification. f .My invention relates to improvements 1n hair drying devices, and has for its ob ect the production of a device of this character which will be of improved construction and eiiicientin operation.

The mventlon conslsts 1n the combmations and arrangements of parts hereinafter I described and claimed.

The invention will be best understood by 2 reference to the accompan ing drawing forming a part of this speci cat1on, aand in which, 1 y Figure 1 is a top planview. of a hair drying device embodying my invention, Fig. 2 is a side elevation thereof, a portion being broken away order to expose underlying parts, Fig. 3 is an enlarged central longitudinal section of the rearward end portion of the device, Fig. 4 is a detail section taken on line H of Fig. 2, and Fig. 5 is an enlargeddetail front elevation of one of the parts of. the device detached.

The preferred form of construction as illustrated in the drawing comprises a comb consisting of a back 1 an teeth 2 projecting from said back, said back and teeth being formed of a single iece of sheet metal which is bent upon itself in the manner shown in Fig. 4, so as to form a chamber 3 and a passage 4 in said back extending longitudinally thereofand substantially par-. allel with each other. Leading from the passage 4 are branch passages 5 which commumcate with the various comb teeth. 2, the

adjacent sides of the latter being provided with grooves 6 which communicate or register with .the branch gassages 5, as clearly shown in Figs. 3 an 4. Mounted in the chamber 3 is an electrical heating element 7 the function of which is to heat the comb back 1 and which in turn is adapted to heat the air forced into the passage 4, before the same-sis discharged through the passages 5 in the hair dryin operation.

'combback 1, as clearly shown in Patented May 4', 1915.

the accommodation of the adjacent Ie nd of i 3. The conductor wires 10 of the heating ele ment 7 terminate in connecting terminals 11 which are mounted in asuitable plug 12 of msulating material which is mounted in an angularly disposed nipple 13 formed for the reception thereof upon the member 8. The terminals 11 are adapted to be connected with any suitable source of electricity, not shown, in order to furnish electrlcal energy to the heating element 7. Interposed in the conductor wires 10 is also a switch 14 of any approved design, that shown in the drawing having laterally extending operating buttons 15 so arranged that when one is depressed the circuit will be closed, and when the other is depressed, the circuit will be opened.

Abutting the rearward end of the member 8 is a bloek'16 of insulating material and extending from said block is a tube 17 held are fastened by means of a connecting rod 18 which extends through said parts longitudinally thereof, the forward end of said rod being provided with a head which en gages against a plate 19 closing the forward end of the comb back 1, the rearward end of said rod being provided with a nut" 20 which engages against a plate 21 closing the rearward end of tube 17. With this arrangement it will be seen that the various parts will be securely clamped together by simply tightening the nut 20.

Rotatably mounted upon, the tube 17 is a nipple or collar 22 held against longitudinal movement between block 16 and a collar 23 which is secured to the rearward end of said tube. The member 22 is yieldingly held in position of rotary adjustment by means of spring pressed balls 24 which are mounted in the front end of said member 22 for engagement with recesses or sockets 25 formed in the adjacent face of block 16. All of said balls and recesses are positioned the same distance from the center of rotation of said parts so that during relative rotary movement of the parts, said balls will be moved to successively engage with the various rethe same will be automatically yieldingly locked.

The passage 4 is extended as shown through the member 8 and leading from the rearward end of said member is a tube 26 held against longitudinal movement by reason of the flanged forward end of said tube engaging against the front side of block 16 and a stop collar 27 provided upon said tube which engages against the outer side of plate 21. Embracing the flared rearward end of tube 26 is a compressible rubber bulb 28 provided at its opposim ends with inlet and outlet openings 29 and 30 respectively which are governed by flap valves 31 and 32 respec tively, so that upon flexing of the bulb 28, air will be drawn through the opening 29 and discharged through the opening 30 into the tube 26 and thence into the passages 4 and 5. Secured to the member 23 is a handle piece 33 the rearward end of which is curved for cooperation with the bulb 28, said member 33 serving also as a guard for said bulb so as to prevent injury thereto.

In use, the device is held by the hand with the palm resting against the member 33 and the fingers engaging the bulb 28. The terminals 11 being connected with a source of electrical energy, when it is desired to operate the device, one of the buttons 15 of the switch'lt is depressed to close the circuit through the heating element 7 The heating element 7 will cause the adjacent walls of the chamber 3 to become heated and which in turn through conductivity will cause heating of the walls surrounding the air passage 4. Through successive flexing or depression of the bulb 28, air will be pumped through the passages 4 and 5, the air while passing through passage 4 being heated through contact with the heated walls of said passage, as will be readily understood. The hot air which issues from the openings 5 coming in contact with the hair will serve to effectively dry the same, as will be understood. Through the tapering formation of the passage 1, a uniform discharge through all of the openings 5 will be insured, the result without this tapering formation, being to secure a high pressure at the openings 5 close to the member 8 and a very low or no pressure at the remote openings. Through the tapering formation the discharging air passage through the passage 4 will be concentrated gradually toward the outer end of said passage with the result of a uniform pressure at the discharge openings 5 being secured, as above mentioned. The provision of a passage for the air separate from the passage or chamber in which the heating element is employed removes all impediment from the air passage and therefore insures a more ready discharge of .the air in the operation of the device. Through the rotary adjusting an air ment which is afforded member 22, handle piece 33 which is connected with the member 22 may be adjusted relative to the comb teeth 2 so as to secure any desired angularity of the comb teeth relative to said hand piece in the operation of the device. This is of special advantage since difi'erent parts of thehair are more readily combed with the comb teeth positioned at certain angles.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
